Breathwork Glossary A–Z: 61 Terms Explained

4

4-7-8 breathing: A paced pattern of inhaling for four counts, holding for seven, and exhaling for eight. It is commonly used for winding down and is often mentioned in sleep-related breathwork.

A

Albumin: The most abundant protein in blood plasma. As blood pH rises, albumin binds more calcium, temporarily reducing the free ionized calcium available to nerves and muscles.
Altered state of consciousness: A temporary shift in perception, emotion, body awareness, or sense of self. Intensive breathing can contribute to such states, but experiences vary widely.

B

Bhastrika: A vigorous yogic practice of forceful, equal inhales and exhales, like a blacksmith's bellows. It strongly activates the nervous system and requires caution with the same contraindications as other intense techniques.
Bioenergetic Analysis: A body-oriented psychotherapy developed by Alexander Lowen and colleagues from the work of Wilhelm Reich. It uses breath, posture, grounding, movement, and expression to explore links between bodily patterns and emotional experience.
Body psychotherapy: A family of psychotherapeutic approaches that includes bodily sensation, posture, movement, and breathing alongside psychological reflection. It influenced several twentieth-century breathwork schools.
Bohr effect: The influence of carbon dioxide and acidity on how readily haemoglobin releases oxygen into tissues. Lower CO₂ can make oxygen release less efficient even when blood oxygen saturation is high.
Box breathing: A paced practice with four equal phases: inhale, hold, exhale, and hold. It is commonly used to steady attention and regulate arousal.
Breath retention: A deliberate pause after an inhale or exhale. Retentions change carbon dioxide and oxygen levels and should be approached gradually, seated or lying down, and never in water or while driving.
Buteyko Method: A breathing-retraining approach from Soviet-era Ukraine and Russia that emphasizes reduced breathing volume, nasal breathing, and breath holds. It is often discussed in relation to asthma and dysfunctional breathing patterns.

C

Carbon dioxide partial pressure: A measure of the pressure contributed by dissolved carbon dioxide in blood. When ventilation exceeds the body’s CO₂ production, this value falls and can initiate respiratory alkalosis.
Carbonic acid: A weak acid formed when carbon dioxide dissolves in water, including blood. When CO₂ falls, less carbonic acid and fewer hydrogen ions are present, so blood pH rises.
Cerebral vasoconstriction: Narrowing of blood vessels in the brain. A rapid fall in CO₂ can cause this response, temporarily reducing cerebral blood flow and contributing to dizziness or light-headedness.
Ceremonial cacao: Minimally processed cacao traditionally used in rituals and group settings. It contains theobromine and is sometimes combined with breathwork; people sensitive to stimulants should approach it mindfully.
Circular breathing: Breathing in a continuous rhythm without intentional pauses between inhale and exhale. The term is used differently in breathwork and in wind-instrument technique.
Coherent breathing: Slow, even breathing near a person’s cardiovascular resonance frequency, often around five to six breaths per minute. It may support heart-rate variability and relaxation.
Conscious Connected Breathing: An umbrella term for intentional, continuous breathing without pauses. Pace, depth, setting, and facilitation differ among schools such as Rebirthing, Holotropic Breathwork, and Vivation.
Contraindication: A health condition or circumstance that makes a practice inadvisable or requires medical approval and adaptation. Contraindications depend on the intensity and mechanics of the technique.

D

Diaphragmatic breathing: Breathing that emphasizes movement of the diaphragm, usually felt as expansion around the lower ribs and abdomen rather than only in the upper chest.

E

Ecstatic Dance: A free-form group dance practice without choreography, substances, or talking on the dance floor. It shares some goals with breathwork — presence, expression, release — but works primarily through movement rather than breath.
Ego dissolution: A temporary weakening of the usual sense of being a separate self. It may feel expansive or unsettling and is a subjective experience, not a guaranteed outcome.

F

Facilitator: A person who prepares, guides, and monitors a breathwork session. Training standards vary, so participants should ask about qualifications, screening, consent, and emergency procedures.
Functional breathing: A broad approach aimed at efficient everyday breathing, commonly emphasizing nasal, diaphragmatic, quiet, and appropriately paced breathing rather than intense altered-state work.

H

Heart-rate variability: The natural variation in time between heartbeats. It reflects several regulatory processes and often changes with breathing rhythm, posture, activity, and stress.
High-ventilation breathwork: An umbrella term for practices that deliberately increase breathing rate, depth, or both enough to lower blood CO₂. Effects and risks depend on intensity, duration, health status, and facilitation.
Holotropic Breathwork: A facilitated method developed by Stanislav and Christina Grof that combines intensified breathing, evocative music, and focused bodywork in an extended group setting.
Human Potential Movement: A broad twentieth-century movement focused on personal growth and experiential learning. Centers such as Esalen brought together contemplative practices, bodywork, group therapy, and altered-state exploration, providing a setting for modern breathwork schools to develop.
Hydrogen ion: A positively charged hydrogen particle written as H⁺. Its concentration helps determine acidity: when CO₂ falls during over-breathing, H⁺ concentration falls and blood pH rises.
Hyperventilation: Breathing more air than the body’s current metabolism requires. This lowers arterial CO₂ and can cause light-headedness, tingling, visual changes, or muscle tightening.
Hypocapnia: An abnormally low level of carbon dioxide in the blood, commonly produced by hyperventilation. It contributes to cerebral vasoconstriction and changes in nerve excitability.
Hypoxia: A state of reduced oxygen availability in tissues. Some breathwork methods deliberately create brief, controlled low-oxygen states through breath holds; this is different from uncontrolled oxygen deprivation and requires caution.

I

Integration: The process of reflecting on an experience and translating useful insights into grounded choices, relationships, or routines after a session.
Interoception: The perception of signals from inside the body — heartbeat, breath, tension, gut feelings. Breathwork often trains this inner sensing, which is linked to emotional awareness and self-regulation.
Ionized calcium: The free, biologically active form of calcium in blood. During alkalosis, more calcium binds to albumin, so ionized calcium temporarily falls and nerves and muscles may become more excitable.

K

Kapalabhati: A traditional yogic cleansing practice of rapid, forceful exhales with passive inhales. It is stimulating and not suitable for everyone, especially during pregnancy or with cardiovascular conditions.

M

Mantra chanting: The rhythmic repetition of sounds, words, or phrases, which naturally lengthens the exhale and involves the voice and breath together. Chanting and singing share physiological effects with slow breathing practices.
Mouth breathing: Breathing primarily through the mouth instead of the nose. Habitual mouth breathing is associated with drier airways, poorer sleep quality, and less efficient breathing; functional breath training usually retrains toward nasal breathing.

N

Nadi Shodhana: A traditional pranayama practice of breathing alternately through each nostril, usually using the fingers to close one side. It is commonly used to settle the mind and balance arousal.
Nasal breathing: Breathing through the nose, which filters, warms, and humidifies air. It also supports nitric-oxide availability and is commonly preferred during rest and low-intensity activity.
Nerve excitability: How readily nerve cells respond to stimulation. A rapid rise in pH and the associated fall in ionized calcium can increase excitability, contributing to tingling, muscle stiffness, or tetany.
Nitric oxide: A gas produced in the nasal passages that widens blood vessels and improves airflow and oxygen uptake. Nasal breathing delivers it to the lungs — one reason nasal breathing is emphasized in functional breath training.

O

Oceanic boundlessness: A research term for an experience of unity, timelessness, positive mood, and softened boundaries between self and surroundings. It can occur in altered states but is not specific to breathwork.
Oxygen Advantage: A contemporary breath-training system by Patrick McKeown, aimed mainly at athletes, using nasal breathing, breath holds, and CO₂-tolerance training to improve breathing efficiency.

P

Physiological sigh: A breathing pattern of two inhales followed by a longer exhale. Spontaneous sighs help reopen collapsed air sacs; deliberate repetitions are also used as a short calming practice.
Pranayama: The diverse breath-regulation practices within yoga traditions. Pranayama includes many distinct techniques and should not be treated as a single breathing pattern.
Psychedelic Breath: A contemporary branded breathwork format that combines active or connected breathing, breath retentions, electronic music, and facilitation to support altered-state experiences without psychedelic substances.
Psychedelic integration: The process of making sense of and applying insights from intense experiences — psychedelic or breathwork-induced — in everyday life. Integration support helps translate an experience into lasting change.

Q

Qigong: A diverse family of Chinese practices combining posture or movement, breathing, and focused attention. Qigong comes from its own cultural and medical traditions and is not simply an early form of modern breathwork.
Quantum Light Breath: A modern connected-breathing practice associated with Jeru Kabbal that combines rhythmic breathing, music, and guided attention. Evidence specific to this branded method is limited.

R

Rebirthing Breathwork: A modern form of conscious connected breathing developed by Leonard Orr in the 1970s. Sessions typically use a relaxed, continuous breath while attention stays with bodily sensations and emotions.
Respiratory alkalosis: A rise in blood pH caused by breathing out CO₂ faster than the body produces it. In intensive breathwork it is generally temporary and reverses as breathing normalizes.

S

Set and setting: The internal mindset ('set') and external environment ('setting') that influence how an experience unfolds. Preparation, trust, privacy, music, and facilitator conduct all contribute.
SOMA Breath: A contemporary branded system combining rhythmic music-led breathing, guided breath retentions, meditation, and group facilitation. Its format differs from older connected-breathing schools such as Rebirthing and Vivation.
Somatic release: A non-diagnostic term for physical expressions such as trembling, movement, tears, sound, or shifts in tension during an embodied practice. These responses do not prove that trauma has been resolved.

T

Tetany: In breathwork, temporary tingling, stiffness, or cramping—often around the hands or mouth—linked to hyperventilation, rising pH, and reduced ionized calcium. Persistent or severe symptoms need medical assessment.
Trance Dance: A movement-based practice combining breath awareness, rhythmic music, and intuitive dance, often with eyes covered. It works with similar mechanisms to breathwork — rhythm, attention, and embodied experience.
Transpersonal psychology: A field of psychology that studies experiences extending beyond the ordinary sense of self, including spiritual and altered-state experiences. It helped shape the framework around Holotropic Breathwork and related practices.
Tummo: A Tibetan Buddhist practice that combines breathing, visualization, and bodily discipline within a wider contemplative tradition. It influenced some modern breathing systems but is not identical to the Wim Hof Method.

V

Vagus nerve: A major nerve in the parasympathetic nervous system involved in heart rate, digestion, and communication between brain and body. Slow breathing can influence vagally mediated regulation.
Vivation: A connected-breathing method created by Jim Leonard in 1979. It emphasizes awareness of sensation, relaxation, and integrating experience rather than pursuing catharsis.

W

Wim Hof Method: A branded system combining cycles of deep breathing and breath retention with cold exposure and mindset training. Breathing exercises must never be practiced in water or while driving.
